Infrasound from a bass?

Does the open F# string produces any (minimal) infrasound (a sound below 16 Hz)? The freq. of low F# is 23.12 Hz, so the octave lower would be an infranote (ultra low F#) with freq. of 11.56 Hz. Would the open F# string be resonated treating with ultra low F# infrasound?
Sorry guys, if the question is stupid but I am just curious.

Hmm...ServoDrive Inc.'s "Contrabass" supposedly
has a useable response down to 14Hz.

I dunno how you could verify it outside a lab environment.
Maybe set up a wall of `em out on the Serengeti plains and
start ta' wailin'. If a herd of elly-phants come a runnin'...
there ya' go . Mind ya' don't hit the "Brown sound". Yeesh!

Thanks notduane, the ServoDrive Inc.'s subwoofer is an interesting thing. Maybe I'll order a pair of them.
Anyway, the infrasound could be quite dangerous. The freq. of human vascular system is 7-8 Hz, so a strong infrasound with this freq. can kill you (internal bleeding)! Ask Pentagon...

I read somewhere that muting the low strings and moving them around over the pickup can create very low frequencies that can trash your speakers in a high power environment. The recommendation was to put a low frequency filter in the circuit to prevent this.

JT, low F#... geez... I guess those of us playing those open low B's need to redefine again...

I built my cabs for flat (-1dB) to 28 Hz, and (-3dB) at 25 Hz, thinking I would never be going lower than 31 Hz (low B). Low F# is down around 23 Hz... hummm baaaby..

The problem with ported boxes is they dramatically unload below the box tuning frequency. Below that frequency, the drivers just flop around like they are in open air. This lets subsonic rumbling destroy the drivers.

yeah, that's why bag end uses closed box enclosures for their elf systems. they then boost the frequencies as they get lower by the same amount and at the same -3db frequency point as the box cuts them, enabling them to be flat down to either 8 Hz or 18 Hz depending on the system.

Yep. That's why the Bag Ends cost the Big Bux, and suck up the power. IMO, the Bag End ELF is the best cabinet engineering available today.

They offer a tighter cone control than can be had with a ported box, with the added benefit of subsonic rumble control.

Lay your wallet on the counter... they might give you back the leather part, but they will keep the green stuff..
